To all whom itmoy conccra." i

Be it known that I, HARRY Mon'rmnn SPECHT, of Skaneateles, inthe countyof Qnon'daga, in the State of New York, have mvent ed new anduse'fulImprovements in Vehicle Wheels, of which taken in connection with thedrawings, is a full, clear, and

tion.

This invention'relates to'certain improveaccompanying exact descripticularly to the tire,

My object is to provide a tincture-proof, and practically indestructible I specially adapted for self-propelled vehicle wheels and bicycles,'asa substitute for the usual pneumatic tire, but which has all thelaminated tire having all appliedthereto.

portion or resiliency and other advantages of the pneu niatic tire,together with the'additional adwhen worn, or otherwise rendered unfitfor use without interfering with the Otl'lGIfySfiC- tions. q r In otherwords, I have sought to produce a the resiliency of the ordinarypneumatic tire and composed of a circular series of springmetalringsembedded or incorporated in some durable, flexible, material, as rubber,

whereby the greater portions of the metal, rings are'concealed andprotected from the elements. I

A furthefiobject isto ,r

fastening means for each gthetiresections or lamina adapted to besecured to-the rim of the wheel in such manner that they may be releasedat any time to permit the re 'moval of any one or more rings or tire sections se arately from the others.

' A still further object is to provide the meeting edges of the'ringswith interfitti ng tongues an grooves whereby a certain degree ofcontinuity is established between the sections or rings so that theresilient action of any one of the rings is transmitted more or less tothe next ad acent'rings.

Other objects and uses will appear in the following description. 4

The rim --'-1 --*may be of any suitable material, such as Wood ormetal,and in this particular-instance, is provided with a con-.- tra'llengthwise rib 5' and oppositelateral. promoting flanges -6-, the rib5.- being' formed with aseries of radialslots -7 corresponding'innumberto the num: ber of tire sections 2- for receiving por -,2

he flanges 6- are formed iii their peripheries with lengthwisegroovesgi;--8- and the rings are formed u on their peripheries with;corresponding y positioned transverse ribs '9-, -Wh ich enter saidgrooves when the rings are placed upon the rim to hold said ringsagainst lateral or transven' e displacement, it being understoodt" t thetransverse contour of the eriphery of the-flanges -6'-is'substantia ythe same as the adjacent. pbrtions of the rin s which are seatedthereon; a l h'e rubber sections -2 of the tire rings are dividedthrough one side and their meeting-ends are spread" or separated adistance flange -5' otzthe rim 1. so as to abut a ainst the o p'ositeside facesof saidflange w e'n-assemb d upon the rim.

The s 1" metal rings -3- are continuous, antith ggreater portion thereofare embedded and concealed within the rubber ring section 2, exce t thatex osed between t emeetrng ends of the in her section -2- this latterportion being preferably solid, while the remaining porcorresponding tothe transverse width of'theportion which is tions inclosed within therubber section the slot 1 and are preferably round in cross section, theouter segment --11-- affording a certain degree or resiliency andresistance while the inner ring segment 121- afiords additionalresilient resistance and acts as a spring buffer for the outer ringsegment 1 1- when the compressionload upon the tire is excessive. Thisis an imortant feature of my invention for the reason that the tire isextremely resilient under a light load, and at the same time theresistance to compression gradually increases un der increasing heavyloads.

The solid portion of the spring metal ring I :-3 exposed between themeeting ends of holding the solid portion the rubber section 2, andwhich is fitted in its corresponding slot -7-- in the rib attachment forthe -5- afiords a means of clamping bolts --4-, and for this purpose isprovided with transverse apertures 13- for receiving pivotal pins 14-:-on the inner ends of the opposite clamping bolts 4', the lat-'- terbeing passed through diverging apertures 15- in the rim 1- and aretightened by clamping nuts 16- which engage the inner face of said rim.

The spring metal rings -'3-% .are held against relative circumferential.movement 'within their inclosing rubber rings --2 by lateralprojections 17- which are secured to the ring and are likewise embeddedand concealed in the rubber rings -2-, thereby of the spring ring '3--in exact registration with the space between. the meeting ends of therubber ring,- although the 'clampin -bolts- 4; serve a similarpurosewhen t e tire sections are accured to "t faces of the rubber tiresections 2-.- are formed. with annular tongues 18-- androoves l9-,thetongues of each section tting' into the grooves of.the adjacentsection, thereby establishing a certain degree-of continuity between theseveral tire sections,

. :whereby'the compression strains on one seetion are transmitted toagreater or less de' gree to the adjacent sections, and thereforerelieves the individual sections from excessive'strains-in passing overobstructions and unevenpavements.

In some instances, I be covered with-a continuous rubber shoe '25 shownin Fig. 1 but I do not wish to belimited. tethe use 0 rim. The oppositemeeting the laminated tire may vention lies more particularly in thelaminated tire, composed of a circular series of rubber rings havinginternal spring metal rings with means for fastening the tire sectionsto the rim.
